3 Most importantly, I want to remind you that in the last days scoffers will come, mocking the truth and following their own desires. 4 They will say, "What happened to the promise that Jesus is coming again? From before the times of our ancestors, everything has remained the same since the world was first created." 5 They deliberately forget that God made the heavens long ago by the word of his command, and he brought the earth out from the water and surrounded it with water. 6 Then he used the water to destroy the ancient world with a mighty flood. 7 And by the same word, the present heavens and earth have been stored up for fire. They are being kept for the day of judgment, when ungodly people will be destroyed.
8 But you must not forget this one thing, dear friends: A day is like a thousand years to the Lord, and a thousand years is like a day.
9 The Lord isn't really being slow about his promise, as some people think. No, he is being patient for your sake. He does not want anyone to be destroyed, but wants everyone to repent. 10 But the day of the Lord will come as unexpectedly as a thief. Then the heavens will pass away with a terrible noise, and the very elements themselves will disappear in fire, and the earth and everything on it will be found to deserve judgment.
Matthew Henry's Commentary on 2 Peter 3:3-10
Commentary on 2 Peter 3:1-4
(Read 2 Peter 3:1-4)
The purified minds of Christians are to be stirred up, that they may be active and lively in the work of holiness. There will be scoffers in the last days, under the gospel, men who make light of sin, and mock at salvation by Jesus Christ. One very principal article of our faith refers to what only has a promise to rest upon, and scoffers will attack it till our Lord is come. They will not believe that he will come. Because they see no changes, therefore they fear not God, Psalm 55:19. What he never has done, they fancy he never can do, or never will do.
Commentary on 2 Peter 3:5-10
(Read 2 Peter 3:5-10)
Had these scoffers considered the dreadful vengeance with which God swept away a whole world of ungodly men at once, surely they would not have scoffed at his threatening an equally terrible judgment. The heavens and the earth which now are, by the same word, it is declared, will be destroyed by fire. This is as sure to come, as the truth and the power of God can make it. Christians are here taught and established in the truth of the coming of the Lord. Though, in the account of men, there is a vast difference between one day and a thousand years, yet, in the account of God, there is no difference. All things past, present, and future, are ever before him: the delay of a thousand years cannot be so much to him, as putting off any thing for a day or for an hour is to us. If men have no knowledge or belief of the eternal God, they will be very apt to think him such as themselves. How hard is it to form any thoughts of eternity! What men count slackness, is long-suffering, and that to us-ward; it is giving more time to hisown people, to advance in knowledge and holiness, and in the exercise of faith and patience, to abound in good works, doing and suffering what they are called to, that they may bring glory to God. Settle therefore in your hearts that you shall certainly be called to give an account of all things done in the body, whether good or evil. And let a humble and diligent walking before God, and a frequent judging of yourselves, show a firm belief of the future judgment, though many live as if they were never to give any account at all. This day will come, when men are secure, and have no expectation of the day of the Lord. The stately palaces, and all the desirable things wherein wordly-minded men seek and place their happiness, shall be burned up; all sorts of creatures God has made, and all the works of men, must pass through the fire, which shall be a consuming fire to all that sin has brought into the world, though a refining fire to the works of God's hand. What will become of us, if we set our affections on this earth, and make it our portion, seeing all these things shall be burned up? Therefore make sure of happiness beyond this visible world.
